G-Series Gaming Keyboards

[majmotoko]

I have had my G110 for a while now, and simply love it. I recently added a G300 gaming mouse to my system, and was forced to update to the new Logitech Gaming Software. I have had nothing but problems since this program installed. If I switch between the mouse and keyboard set up in the LGS, my mouse moves super slow and I have to reset it constantly. My G Keys don't work 75% of the time. To make matters worse, my computer no longer registers my keyboard to allow me to log in. I now have to have two keyboards plugged in to my computer in order to log in and use it. I tried installing the legacy software for that results in the keyboard not working at all, and if I remove the LGS the keyboard also does not work. I've searched and read through the forums, and have not found an answer to my situation. Help would be greatly appreciated as I do not believe that anyone should have to use one keyboard to log in and one keyboard to game, and then constantly reset everything just to get things to work for 5 minutes.

HELP!!!
